Description

Technical Field

[0001] This invention relates to a handle mechanism, and more particularly to a handle mechanism for an aircraft door. Background Technology

[0002] Previously, a handle mechanism for opening and closing an aircraft cabin door was known, including an inner handle, an outer handle, and a connecting structure between the inner and outer handles. By rotating the inner handle, the corresponding protrusion 104 of the cam portion 34 in the connecting structure escapes from the triangular recess 90 of the cylindrical cover 32 that it fits with. At the same time, the protrusion 106 on the other end of the cam portion 34 escapes from the triangular recess 96 of the outer handle 26 that it fits with, so as to pop out the outer handle and drive the outer handle to rotate together, thereby opening the cabin door.

[0003] As described above, the aforementioned handle mechanism can only eject the outer handle from the handle slot from the inside of the hatch, and cannot eject the outer handle from the handle slot from the outside of the hatch. Therefore, the hatch can only be opened from the inside of the hatch using the inner handle, and cannot be opened from the outside of the hatch using the outer handle.

[0004] Moreover, in the aforementioned handle mechanism, when the hatch is opened from the inside using the inner handle, the inner handle will cause the outer handle to rotate together and cannot rotate independently, thus making the opening action more difficult. Summary of the Invention

[0005] The present invention was made in view of the above-mentioned technical problems, and its purpose is to provide a handle mechanism that can open the hatch from the inside by means of the inner handle, making the opening action easy, and can also open the hatch from the outside by means of ...

[0006] To achieve the above objectives, a first aspect of the present invention provides a handle mechanism, a handle box installed on a cabin door, comprising: an inner handle; an outer handle, the outer handle being reciprocally movable within the handle box; a connecting structure capable of connecting or separating the inner handle from the outer handle; and an outer handle ejection structure, the outer handle ejection structure being configured to eject the outer handle from the handle box, the connecting structure comprising: a handle rocker arm, the handle rocker arm being sleeved on the outer periphery of the cylindrical body of the outer handle, capable of rotating synchronously with the inner handle, and forming a radially extending first connecting hole; and a second connecting hole penetrating the outer handle body formed in the outer handle. The second connecting hole is radially aligned with the first connecting hole; a radially extending positioning hole is formed in the outer handle pop-out structure, the positioning hole being radially sandwiched between the first connecting hole and the second connecting hole; and a sliding connector is arranged to reciprocate radially within the first connecting hole, the positioning hole, and the second connecting hole, the sliding connector being reciprocating between a first position and a second position, the first position being the position where the sliding connector is fully slid out of the first connecting hole and into the positioning hole and the second connecting hole, and the second position being the position where the sliding connector is fully slid out of the second connecting hole and into the positioning hole and the first connecting hole.

[0007] According to the above structure, by sliding the slider in the first connecting hole, the positioning hole and the second connecting hole, the inner handle and the outer handle can be separated or connected, so that the inner handle can be rotated independently inside the hatch and the outer handle can be rotated outside the hatch to drive the inner handle.

[0008] The handle mechanism of the second aspect of the present invention is based on the handle mechanism of the first aspect of the present invention. The outer handle pop-out structure includes: a sleeve portion, which is nested from one side of the axial direction into the outer peripheral side of the outer handle and the inner peripheral side of the handle rocker arm, and is composed of a bottom portion and a wall portion, the bottom portion being fixed to the handle rocker arm, and the wall portion being between the outer handle and the handle rocker arm; an outer handle spring, which connects the bottom portion of the sleeve portion to the outer handle; an outer handle pressing portion, which is nested in the outer handle by pressing the outer handle from the other side of the axial direction, and has a first driving portion capable of driving the sliding connector from the other side of the axial direction; and an outer handle pressing spring, which connects the outer handle to the outer handle pressing portion. When the sliding connector moves to the first position, the first driving portion abuts against the sliding connector from the other side of the axial direction in the positioning hole.

[0009] According to the above structure, by forming an outer handle pop-out structure consisting of a sleeve part, an outer handle spring, an outer handle pressing part, and an outer handle pressing spring, when the sliding connector moves to the first position, not only can the inner handle be separated from the outer handle, but the first drive part can also abut against the sliding connector from the other side of the axial direction to fix the sliding connector in the axial direction, thereby locking the outer handle in the first position through the sliding connector.

[0010] The handle mechanism of the third aspect of the present invention is based on the handle mechanism of the second aspect of the present invention, wherein the first drive portion is formed as an inclined surface that is inclined relative to the axial direction, the inclined surface extends radially to the sleeve portion and is capable of reciprocating axially in the first drive hole.

[0011] According to the above structure, by forming the first driving part as an inclined surface that is inclined relative to the axial direction, and the inclined surface extends radially to the sleeve part and can reciprocate along the axial direction in the first driving hole, it can be ensured that when the first driving part moves from the other side of the axial direction, its inclined surface can abut against the slider and drive the slider to move radially outward.

[0012] The handle mechanism of the fourth aspect of the present invention is based on the handle mechanism of the third aspect of the present invention, wherein when the outer handle is in the second position, the sliding connector is pressed against the outer peripheral surface of the outer handle.

[0013] According to the above structure, by pressing the sliding connector against the outer peripheral surface of the outer handle when the outer handle is in the second position, the axial fixation of the outer handle can be further ensured by pressing the sliding connector against the outer peripheral surface of the outer handle, on the basis of fixing the axial position of the outer handle by the connecting structure.

[0014] The handle mechanism of the fifth aspect of the present invention is based on the handle mechanism of the fourth aspect of the present invention, and further includes a second driving part. The second driving part is disposed on the radially outer side of the sliding connector, and is composed of a steel ball in contact with the sliding connector and a sliding spring in contact with the steel ball, and always applies force to the sliding connector radially inward.

[0015] According to the above structure, by providing a second driving part on the radially outer side of the sliding connector and configuring the second driving part to consist of a steel ball and a sliding spring, a force can be applied to the sliding connector radially inward through a simple structure.

[0016] The handle mechanism of the sixth aspect of the present invention is based on the handle mechanism of the first aspect of the present invention, wherein the first position is a position where the outer surface of the outer handle is flush with the outer surface of the handle box, and the second position is a position where the outer surface of the outer handle pops out from the outer surface of the handle box.

[0017] According to the above structure, by setting the first position to be flush with the outer surface of the outer handle and the outer surface of the handle box, and setting the second position to be the position where the outer surface of the outer handle pops out from the outer surface of the handle box, the outer handle can be kept in the first position while the inner handle and the outer handle are separated, and the outer handle can be kept in the second position while the inner handle and the outer handle are connected.

[0018] The seventh aspect of the handle mechanism of the present invention is based on the handle mechanism of the second aspect of the present invention, wherein the sleeve portion has an elongated hole extending along the axial direction in the sleeve wall portion, and the cylindrical outer handle body of the outer handle has a circular hole formed in a range that always overlaps with the elongated hole as the outer handle moves relative to the sleeve portion, and an outer handle pin is inserted into the elongated hole and the circular hole.

[0019] According to the above structure, the sleeve portion and the outer handle can be connected in a simple structure by means of an elongated hole formed in the sleeve portion extending axially, a round hole formed in the outer handle body of the outer handle and overlapping the elongated hole in the axial direction, and an outer handle pin inserted in the elongated hole and the round hole, and the range of movement of the outer handle relative to the sleeve portion in the axial direction can be limited.

[0020] The handle mechanism of the eighth aspect of the present invention is based on the handle mechanism of the seventh aspect of this aspect, wherein the elongated hole is formed in such a way that when the outer handle is in the first position, the outer handle pin abuts against the inner edge of the hole on one side of the axial direction of the elongated hole, and when the outer handle is in the second position, the outer handle pin abuts against the inner edge of the hole on the other side of the axial direction of the elongated hole.

[0021] According to the above structure, by configuring the elongated hole, the round hole, and the outer handle pin such that when the outer handle is in the first position, the outer handle pin abuts against the inner edge of the hole on one side of the axial direction of the elongated hole, and when the outer handle is in the second position, the outer handle pin abuts against the inner edge of the hole on the other side of the axial direction of the elongated hole. This abutment of the outer handle pin against the inner edge of the hole on one side of the axial direction of the elongated hole and against the inner edge of the hole on the other side of the axial direction of the elongated hole assists in fixing the outer handle in the first and second positions. Therefore, the outer handle can be more reliably confined to reciprocating movement between the first and second positions and fixed in both positions.

[0022] The handle mechanism of the ninth aspect of the present invention is based on the handle mechanism of the third aspect of the present invention, wherein the inner circumferential surface of the handle rocker arm is formed with a stepped portion, and the bottom of the sleeve portion abuts against the stepped portion in a manner that allows it to rotate freely.

[0023] According to the above structure, by forming a stepped portion on the inner circumferential surface of the handle rocker arm, and by having the bottom of the sleeve portion abut against the stepped portion in a freely rotatable manner, the inner handle and the handle rocker arm can rotate freely relative to the sleeve portion. This ensures that when the inner handle is separated from the outer handle, the rotation of the inner handle will not be transmitted to the outer handle through the sleeve portion, and ensures that the inner handle can be turned independently from inside the hatch.

[0024] The handle mechanism of the tenth aspect of the present invention is based on the handle mechanism of any one of the first to ninth aspects, wherein the inner handle is rotatable relative to and airtightly connected to the handle box via the handle rocker arm. Attached Figure Description

[0078] The following is for reference Figures 1 to 5 Various embodiments and variations thereof of the handle mechanism 100 of the present invention will be described.

[0079] The handle mechanism of the present invention is a mechanism for opening and closing aircraft cabin doors. For the sake of simplicity, the following description and drawings omit the connection mechanism between the handle mechanism and the cabin door, as well as the description of how the rotation of the inner and outer handles drives the opening and closing of the cabin door via an intermediate mechanism.

[0080] In the handle mechanism 100 of the present invention, the cylindrical inner handle body 12 of the inner handle 1 and the cylindrical outer handle body 21 of the outer handle 2 are coaxially arranged. Therefore, in the following description, for ease of explanation, as follows... Figure 1 As shown, the direction of the central axis of the inner handle 1 and the outer handle 2 is set as the Z direction, one side of which is set as the Z1 side and the other side as the Z2 side. The direction orthogonal to the direction of the central axis is set as the X direction, one side of which is set as the X1 side and the other side as the X2 side.

[0081] (First Implementation)

[0082] (Overall structure of handle mechanism 100)

[0083] Figure 1 This is a schematic diagram showing the general components of the handle mechanism. Figure 2 (A) is a schematic diagram showing the handle mechanism of the first embodiment in a state where the outer surface of the outer handle is flush with the outer surface of the handle case. Figure 2 (B) shows the plane AA. Figure 2 The cross-sectional view obtained by cutting the handle mechanism shown in (A). Figure 1 , Figure 2 (A) and Figure 2 As shown in (B), the handle mechanism 100 includes: an inner handle 1, which includes a cylindrical inner handle body 12 and a gripping portion 11 extending outward from the inner handle body 12; an outer handle 2, which includes a cylindrical outer handle body 21, which is embedded in the handle box 5 in a manner that allows relative movement with respect to the handle box 5; a connecting structure 3, which can connect or separate the inner handle 1 and the outer handle 2; and an outer handle ejection structure 4, which can eject the outer handle 2 from the outer surface of the handle box 5 (i.e., Figure 3 The Z2 side surface of the handle arm 31 pops out; and the handle bracket 6 includes a cylindrical bracket body 61 sleeved on the outer periphery of the handle rocker arm 31 and a bracket periphery 62 extending radially outward from the bracket body 61, the bracket periphery 62 being fixed to the hatch (not shown).

[0084] like Figure 2 and Figure 3 As shown, the inner handle body 12 of the inner handle 1 and the outer handle body 21 of the outer handle 2 are coaxially arranged. Specifically, the inner handle body 12 is roughly cap-shaped, including a bottom wall portion 121 and a peripheral wall portion 122. The outer peripheral end of the bottom wall portion 121 is fitted into the stepped portion 312 on the inner peripheral surface of the end of the handle rocker arm 31 on the Z1 side. The inner handle 1 and the outer handle 2 are fixed together by bolt members (not shown). They can rotate relative to the handle box 5, and the Z2 side end face of the handle rocker arm 31 ( Figure 2 , 3 The lower end face of the handle box 5 is rotatably connected to the Z1 side end face of the handle box 5. Figure 2 , 3 (The upper surface of the middle) is in contact.

[0085] In this embodiment, to ensure the airtightness between the inner handle 1 and the outer handle 2, such as Figure 2As shown, the connections between the inner handle body 12, the handle rocker arm 31, and the handle box 5 are airtight. Specifically, the connections between the inner handle 1 and the stepped portion 312 of the handle rocker arm 31, and between the Z2 side end face of the handle rocker arm 31 and the Z1 side end face of the handle box 5, are all airtight. This ensures the airtightness of the storage space enclosed by the inner handle body 12, the handle rocker arm 31, and the handle box 5.

[0086] like Figure 2 and Figure 3 As shown, an outer handle ejection structure 4 capable of ejecting the outer handle 2 is housed within the aforementioned space. The outer handle ejection structure 4 includes a sleeve portion 45, which is formed to include a bottom portion 451 and a wall portion 452 extending from the bottom portion 451 towards the Z2 side. The bottom portion 451 protrudes radially outward relative to the outer peripheral surface of the wall portion 452, and its protruding portion engages with the stepped portion 312 of the handle rocker arm 31 (e.g., ...). Figure 2 (As indicated by the dashed circle in the diagram), that is, the Z1 side end is fitted into the stepped portion 312 of the handle rocker arm 31; the outer handle spring 44, one end of the outer handle spring 44 on the Z1 side is connected to the inner circumferential surface of the bottom 451 of the sleeve portion 45, and the other end on the Z2 side is connected to the Z1 side end face of the outer handle body 21 of the outer handle 2 to elastically support the outer handle 2; the outer handle pressing portion 42, the outer handle pressing portion 42 is disposed inside the outer handle 2, including the outer handle button 421 nested inside the outer handle 2 and the outer handle pressing stop 422 formed integrally with the outer handle button 421 and in a trapezoidal shape in the XZ plane; and the outer handle pressing spring 43, the outer handle pressing spring 43 is disposed inside the outer handle 2 and sandwiched between the outer handle 2 and the outer handle pressing portion 42, one end of its Z1 side is connected to the bottom surface of the Z1 side of the outer handle body 21 of the outer handle 2, and the other end on the Z2 side is connected to the outer handle pressing portion 42.

[0087] In this embodiment, both the outer handle spring 44 and the outer handle pressing spring 43 are compression coil springs.

[0088] In the aforementioned external handle pop-out structure 4, as Figure 3 As shown, an elongated hole 4521 extending along the axial direction Z is formed in the sleeve portion 45's cylindrical wall portion 452, and a circular hole 212 is formed in the outer handle body 21 of the outer handle 2. The circular hole 212 and the elongated hole 4521 always overlap in the axial direction Z. An outer handle pin 46 is inserted through the elongated hole 4521 and the circular hole 212. By moving the outer handle pin 46 within the axial range of the elongated hole 4521, the outer handle 2 is slidably connected to the sleeve portion 45.

[0089] Moreover, when the outer handle 2 moves to Figure 2In the first position shown, the outer handle pin 46 slides in the elongated hole 4521 until it abuts against the inner edge of the hole on the Z1 side of the elongated hole 4521, and the outer handle 2 moves to... Figure 3 In the second position shown, the outer handle pin 46 slides in the elongated hole 4521 until it abuts against the inner edge of the hole on the Z2 side of the elongated hole 4521. In this way, the range of movement of the outer handle 2 relative to the sleeve portion 45 in the axial Z direction can be limited by the elongated hole 4521 formed in the sleeve portion 45, the circular hole 212 formed in the outer handle body 21 of the outer handle 2, and the outer handle pin 46 inserted in both.

[0090] Moreover, such as Figure 4 As shown, a generally T-shaped positioning hole 4522 is formed in the sleeve wall portion 452 of the sleeve portion 45. The positioning hole 4522 includes Figure 2 At the first position shown, a sliding connection hole 4522A is sandwiched between the second connection hole 211 of the outer handle body 21 of the outer handle 2 and the first connection hole 311 of the handle rocker arm 31 in the X direction, for the slider 32 to reciprocate in the X direction, and a first drive hole 4522B extends from the sliding connection hole 4522A to the Z2 side and for the outer handle pressing block 422 to reciprocate in the axial Z direction.

[0091] Furthermore, in the aforementioned outer handle pop-out structure 4, the outer handle pressing stop 422 is as follows: Figure 2 , 3 The button 421 fixed to the outer handle shown has a trapezoidal cross-section in the XZ plane, which includes an upper bottom surface 4221, a lower bottom surface 4222, and two inclined surfaces 4223. The inclined surfaces 4223 are inclined relative to the Z direction and extend in the X direction to the sleeve wall portion 452 of the sleeve portion 45. They are aligned in the Z direction with the first drive hole 4522B of the positioning hole 4522 of the sleeve wall portion 452.

[0092] Furthermore, as the connection structure 3, in this embodiment, such as Figure 2 The diagram shows a handle rocker arm 31 with a first connecting hole 311 extending radially X. A compression spring 34 is housed within this first connecting hole 311. One radially inner end of the compression spring 34 is connected to a slider 32 (i.e., a sliding connector) via a steel ball 33, while the radially outer end is airtightly sealed by a sealing cap 35. A sliding connecting hole 4522B (see reference) is formed in the sleeve wall portion 452 at a location corresponding to the first connecting hole 311, allowing the slider 32 to enter and exit. Figure 4 ); and in the outer handle 2 at Figure 2In the first position shown, a second connecting hole 211 is formed at the part of the outer handle body 21 corresponding to the sliding connecting hole 4522A. The first connecting hole 311, the sliding connecting hole 4522A and the second connecting hole 211 are continuous from the radially outer side to the radially inner side, allowing the slider 32 to reciprocate within them.

[0093] By setting the connection structure 3 as described above, the outer handle 2 can slide to... Figure 2 In the first position shown, the slider 32 slides radially inward from the first connecting hole 311 of the handle rocker arm 31 until it is completely slid out of the first connecting hole 311, and the outer handle 2 separates from the inner handle 1. Thus, when the operator rotates the inner handle 1 from inside the hatch so that it rotates together with the handle rocker arm 31, the synchronous rotation of the inner handle 1 and the handle rocker arm 31 will not be transmitted to the outer handle 2. Therefore, the inner handle 1 can be operated independently from inside the hatch.

[0094] Furthermore, when the operator presses and releases the outer handle button 421 on the outer handle pressing part 42 from outside the hatch, the outer handle 2 pops out from the handle box 5 and moves to... Figure 3 In the second position shown, firstly, the outer handle pressing stop 422 of the outer handle pressing part 42 enters from the Z1 side into the first drive hole 4522B of the positioning hole 4522 of the sleeve part 45's wall part 452, and continues to slide in the first drive hole 4522B until it abuts against the slider 32, pushing the slider 32 to move radially outward, and then completely slides out from the second connecting hole 211 and enters the sliding connecting hole 4522A and the first connecting hole 311. Next, after the outer handle pressing part 42 is released, under the restoring force of the outer handle spring 44 of the outer handle pop-out structure 4, the outer handle 2 moves towards the Z2 side. At the same time, the slider 32 stops moving radially outward and turns to move radially inward, with the inner circumferential surface of the slider 32 pressing against the outer circumferential surface of the outer handle 2. At this time, the outer handle 1 is connected to the inner handle 1 via the connecting structure 3. When the operator rotates the outer handle 2 from outside the hatch, the rotation of the outer handle 2 can drive the inner handle 1 to rotate synchronously via the connecting structure 3.

[0095] Furthermore, the connection structure 3 described above, combined with the outer handle pop-out structure 4, not only connects the inner handle 1 to the outer handle 2, but also locks the outer handle 2 onto its outer surface 22 (i.e., Figure 2 The surface of the Z2 side shown) and the outer surface 51 of the handle box 5 (i.e. Figure 2 The first position flush with the surface of the Z2 side shown, and its outer surface 22 (i.e. Figure 3 The surface on the Z2 side shown acts as a second position that pops out from the outer surface 51 of the handle box 5.

[0096] Specifically, such as Figure 2As shown, when the slider 32 moves to the first position, the portion of the slider 32 located in the sliding connection hole 4522A of the positioning hole 4522 is fixed in the axial direction Z, and the portion of the slider 32 located in the second connection hole 211 is also fixed in the axial direction. At this time, the outer handle 2 is fixed at a position where its outer surface 22 is flush with the outer surface 51 of the handle box 5.

[0097] like Figure 3 As shown, when the slider 32 moves to the second position, the portion of the slider 32 located between the positioning hole 4522 and the first connecting hole 311 is fixed in the axial direction Z, and the remaining portion of the slider 32 is pressed against the outer peripheral surface of the outer handle 2 under the restoring force of the compression spring 34. At this time, the outer handle 2 is fixed in the axial direction Z via the outer handle ejection structure 4 and the pressing between the slider 32 and the outer handle 2. Thus, the outer handle 2 can be fixed at the position where its outer surface 22 is ejected from the outer surface 51 of the handle box 5.

[0098] (Technical effects of this embodiment)

[0099] According to the handle mechanism 100 configured as described above, when the outer handle 2 is stored in the handle box 5, the inner handle 1 can be separated from the outer handle 2 so that the operator can turn the inner handle 1 independently from inside the hatch, and when the outer handle 2 pops out from the handle box 5, the inner handle 1 can be connected to the outer handle 2 so that the operator can turn the outer handle 2 from outside the hatch.

[0100] Furthermore, when the outer handle 2 is stored in the handle box 5, it can be fixed in a flush position within the handle box 5, and when the outer handle 2 pops out of the handle box 5, it can be fixed in that pop-out position.

[0101] (A variation of the first embodiment)

[0102] In the first embodiment, the structure and technical effects of the handle mechanism 100, which includes an inner handle 1, an outer handle 2, a connecting structure 3, and an outer handle pop-out structure 4, are described in detail.

[0103] In this modified example, except for the different mating structure between the outer handle pressing stop and the inner circumferential surface of the outer handle pressing part compared to the first embodiment, the rest of the parts are the same as in the first embodiment.

[0104] Specifically, such as Figure 5As shown, the dimension of the inclined surface 4223A of the outer handle pressing stop 422A in the Z-axis direction is larger than the dimension of the inclined surface 4223 of the outer handle pressing stop 422 in the Z-axis direction of the first embodiment. When the slider 32 moves to the position where the outer surface 22 of the outer handle 2 is flush with the outer surface 51 of the handle box 5, a portion of the inclined surface 4223A of the outer handle pressing stop 422A on the Z1 side abuts against the inclined guide portion 213A formed on the inner peripheral surface of the outer handle body 21A of the outer handle 2A, and at the same time, a portion of the inclined surface 4223A on the Z2 side abuts against the inner peripheral surface of the slider 32. Thus, compared with the first embodiment described above, the outer handle 2 can be guided to the first position more reliably.

[0105] According to this modified example, in addition to achieving the same effect as the first embodiment described above, where the inner handle can be rotated independently from inside the hatch and the outer handle can be rotated from outside the hatch to cause the inner handle to rotate synchronously, the outer handle 2 can be guided to the first position more reliably.

[0106] The various embodiments and their modifications of the present invention have been described in detail above. However, in addition to the technical solutions described in the above embodiments and their modifications, the elements of the above embodiments and their modifications can be combined to obtain the technical solutions of the present invention without departing from the spirit of the invention.

[0107] In the above embodiments and their variations, a slider is used as a sliding connector, but the present invention is not limited to this and other shapes may also be used.

[0108] In the above embodiments and their variations, a compression helical spring is used in the outer handle pop-out structure to drive the outer handle to reciprocate in the axial direction. However, the present invention is not limited to this, and other driving components such as cylinders can also be used to drive the outer handle to reciprocate in the axial direction.

[0109] In the above embodiments and their variations, the positioning hole of the sleeve portion is formed in a generally T-shape, but the present invention is not limited to this. As long as it includes a sliding connection hole for the sliding connector to enter and exit and a first drive hole for the outer handle pressing block of the outer handle pressing portion to enter and exit, it can also be formed in other shapes.

[0110] In the above embodiments and their variations, the first driving part for driving the sliding connector is a sliding spring connected to the sliding connector via a steel ball. However, the present invention is not limited to this and other configuration methods may also be used.

[0111] In the above embodiments and their variations, the axial movement range of the outer handle relative to the sleeve is limited by using an elongated hole formed in the sleeve portion, a round hole formed in the outer handle, and an outer handle pin inserted in the elongated hole and the round hole. However, the present invention is not limited to this and other methods may also be used.

[0112] In the above embodiments and their variations, the inner handle and the outer handle are fixed together by bolts, but the present invention is not limited to this and other fixing methods can also be used.

[0113] In the above embodiments and their variations, the shape of the outer handle pressing block in the XZ plane is set to trapezoidal as the second driving part of the driving sliding connector. However, the present invention is not limited to this. As long as it extends radially to the sleeve part, it can also be set to other shapes such as rectangle.
